DA14531 The SDK sample code becomes an endless loop..

Question

Hi There, 
 I changed some of the sample code in the 1 step. Then, in the 2 step, the program enters an endless loop(see below). 
 
 If I don't change the code in step 1, the program will report an error(see below). The program crashes at the 1 step of the diagram below. And I don't know the meaning of the 2 marked on the following picture.

Please assist since I totally dunno what to do. Thanks. 
 Best Regards, 
 NX

Hi NX, Thank you for posting your question online.

 From the screenshot you shared we can see that you have modified the SDK folders. We do not support any changes on the SDK. You should be able to create your application on the user folders. For instance on the prox_reporter example: Please work on a clean SDK to avoid any changes made in the SDK folders. Best Regards, OV_renesas
